A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
It can process many materials such as chemical materials, Chinese herbal medicine including root herb, branch, and lump material, various low oil content grain and other solid and brittle materials. The alveoli in the crushing chamber are precisely handled for a smooth surface, thus minimizing powder accumulation and making the crushing chamber
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
Grinding, or abrasive machining, is the process of removing metal in the form of minute chips by the action of irregularly shaped abrasive particles. These particles may be in bonded wheels, coated belts, or simply loose. Grinding wheels are composed of thousands of small abrasive grains held together by a bonding material.
Any of the particles in the layer are subjected to extrusion from adjacent particles in all directions. Particles in the great pressure when the strain occurs, resulting in crushing and microcrack effect, the socalled grain crushing effect. This process is granule crushing process theory, the crushing of the formation of granulation layer
The present chapter will be devoted to a study of the process of grinding within a real mill. Since within a "tumbling" type of mill the size reduction can result from direct crushing, from shearing or abrasion between the particles in the feed, between the particles in the feed and the mill bodies or between the particles and the mill

Therefore, improving the grinding process is an effective way to achieve high efficiency, low consumption and increase economic benefits. 1 more broken and less grinding process The crushing of materials is mainly achieved by the extrusion and impact of the equipment on the minerals, and the grinding is mainly achieved by the impact, grinding
The mantle oscillates, causing a decrease in the volume between the mantle and the concave casing and crushing the material. The crushed material then exits freely from the apparatus. Rolls During the crushing operation, the two rolls rotate toward each other, resulting in crushing. The feed particle size determines the type of rollers used.
